ABSTRACT.
A detailed deuterium excess profile measured along the Dome C EPICA (European Project for Ice Coring in
Antarctica) core reveals the timing and strength of the sea surface temperature changes at the source regions
for Dome C precipitation. We infer that an Oceanic Cold Reversal took place in the southern Indian Ocean,
800 years after the Antarctic Cold Reversal. The temperature gradient between the oceanic moisture source
and Antarctica is similar to the Dome C sodium profile during the deglaciation, illustrating the strong link
between this gradient and the strength of the atmospheric circulation.
